摘要 目的探讨前列腺良、恶性病变在经直肠超声(TRUS)、磁共振成像(MRI)中的影像学表现,评价TRUS联合MRI对前列腺良、恶性病变的定性诊断价值。方法选取63例临床表现有前列腺疾病的患者行TRUS及MRI检查,对超声图像及MRI图像表现行血管半定量分型定量分析。结果①良、恶性病变在发生部位、边界、回声类型、及对包膜等方面的影像具有显著差异(P<0.01);经直肠彩色多普勒血流(CDFI)显示前列腺癌(PCa)较前列腺增生(BPH)血管丰富、增粗、走形迂曲、紊乱;③TRUS诊断PCa的敏感性为72.73%,特异性为83.33%,符合率为77.78%;MRI诊断PCa的敏感性为81.82%,特异性为83.33%,符合率为82.54%;TRUS联合MRI诊断PCa的敏感性90.91%,特异性为93.33%,符合率为92.06%。结论TRUS联合MRI可提高前列腺良、恶性病变的诊断率,可为前列腺良、恶性病变的鉴别诊断提供更加丰富的诊断信息。
